Cutting phaseWhen the protruding peak of holystone surface and coarse raceway surface is contacted, because osculatory area is lesser, the pressure on unit area is greater, below constant pressure action, holystone gets above all of workpiece " a traditional method of indicating the pronunciation of a Chinese character by using two other Chinese characters is cut " action, make the part of holystone surface grinds bead to fall off with disintegrate, show a few new grind bead and blade edge ......

切削阶段磨石表面与粗糙滚道表面的凸峰接触时，由于接触面积较小，单位面积上的压力较大，在一定压力作用下，磨石首先受到工件的"反切削"作用，使磨石表面的部分磨粒脱落和碎裂，露出一些新的锋利的磨粒和刃边。与。。。。。。

2Graduate School of Chinese Academy of Sciences, Beijing 100049, ChinaAbstract: Two sets of dehydrationmelting with a natural solid amphibolite(56vol.% hornblende, 43vol.% plagioclase), collected from the DabainengLeyu profile in the southern Ailaoshan orogenic belt, Honghe County, Yunnan Province, have been carried out in multianvil apparatus(YJ3000t and JL3600t) at 1035 GPa and 950 ℃ for 20300 h. One is keeping the temperature at 950 ℃ and the annealing time of 100 h, varying the pressure (1035 GPa). The other is keeping the pressure at 30 GPa and temperature at 950 ℃, varying the annealing time (20300 h). The products are inspected with microscope and electron probe.

By field-testing methods, such as static cone penetration test, field vane shear test, and pore water piezometer test, the variation of strength and the pore water pressure are measured at real time, and the marine hydrodynamics' impaction on the consolidation process of the sediments in the Yellow River Estuary was studied. It is shown that the self-consolidated sediments have a very fast consolidation rate, under self-consolidation, in 72h, the consolidation degree reaches 37% and about 142h the pore water pressure disperse over, while under the hydrodynamics, in 72h the consolidation degree reaches 52% and about 195h the pore water pressure disperse over.

在黄河三角洲刁口叶瓣潮坪上，开挖2m×1m×1m的试坑，现场取土配置黄河口快速沉积形成的流体状堆积物，以铁板部分覆盖试坑隔绝波浪和潮流作用，利用微型贯入、静力触探、十字板剪切试验、孔隙水压力监测等原位测试手段，实时测定快速沉积的海床土强度发展以及孔隙水压力消散情况，研究快速沉积的粉质海床土分别在自重条件下以及在波浪和潮波等水动力作用下的固结过程。

The test results show the principle of variation of pressures on culverts beneath high fill is similar, it is that, even if the embankment is filled up to a higher height, the earth pressures can still partly transfer to the top of culvert, as a result the pressures on the culvert increase nonlinearly with the variation of height of fill and further the pressures are obviously lower than theoretical value by σ=γH.

模型试验和数值模拟计算结果表明，当填土达到一定高度后，高填方涵洞上方将产生明显的拱效应，但由于涵洞填土为破碎的岩土，其拱效应与岩石中开挖洞室上方的拱效应不同，高填方涵洞上方填土产生的"土拱"效应具有不稳定的特点，表现为随着填土高度的增加仍有部分土压力传递到涵洞上，涵顶土压力随填土高度成非线性增加。

Partial fracturing wells in Sulige Gasfield produces massive sand slurry because of unreasonable proration during their production. Some phenomena occur such as a lot of sand production, accumulation in wellbore, off production due to watered out, and yield decline as well as pressure drop, resulting in influencing the production result to a great extent.

中文摘要：苏里格气田部分压裂井在生产中因配产不合理出现了：①产量过大导致生产大量出砂影响生产；②气井生产流量达不到携带井底积液的要求，区块内出现较大一批积液井、水淹井；③由于配产不合理致使气井生产无稳产期，投产后压力、产量直线下降至废弃压力生产阶段，极大程度上影响了气井的生产效果。

To obtain the approximate solution, the pressure acting on the gate is divided into two parts, one is the fluctuating pressure of the flow underneath the stationary gate, which is investigated with experiment; the other is the hydrodynamic pressure due to the vibration, which is equivalent to the attached mass matrix, damping matrix and stiffness matrix of the equation.

为了获得方程的近似解，本文将作用在闸门上的水动力荷载分为两个部分，一是闸门无振动时的水流压力，用水力模型试验测定；二是由于闸门振动引起流场扰动的动水压力，通过运动方程中的附加质量阵，附加阻尼阵和附加刚度阵来等效。
